Application filed July 22, 1914. Serial No. 852 .350.

Be it known that we, \ViLLIAii SHAKES- PEARE, Jr., and WILLIAM Sciiiin), citizens of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Carbii eters, of which the following is a specification.

This invention relates to improvements in carbureters.

The main objects of this invention are: First, to. provide an improved carbureter in which the proper relative proportions of fuel and air are maintained throughout varying running conditions of the engine. Second, to provide an improved carbureter in which the air and fuel valves are simultaneously operated or the fuel valve may be independently operated and adjusted. Third, to provide an improved carburetor which is capable of being adjusted for proportioning the air and fuel and one in which the proportion is maintained throughout the scope of adjustment of the throttle. Fourth, to provide in a carburetor, an improved valve mechanism'which is notlikely to get out of repair or ad ustment in use and one which is very simple and easy to operate.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure whichis a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Fig. VI is an enlarged detail horizontal section through the valve operating mechanism on a line corresponding to line 6-6 of Fig. I; Fig. VII is a detail plan view of the yalve operating mechanisms with the cap 0 removed. Fig. VIII is a detail perspective view of the valve operating mechanisms with the cap 70 removed. Fig. IX is a perspective View of the member or plate 58 of the'auxiliary valve actuating means. Fig. X is a detail vertical section through the valve actuating means on a line corresponding to line 1010 of Fig. VII. Fig. is a front View of the fuel and air regulating levers. Fig. XII, is a detail vertical section on a line corresponding to liiie 1212 of Fig. XI.

'In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

. Referring to the drawing, the body of our improved carbureter asshown, for convenience in manufacturing and assembling, con

.sists of members 1, 2 and 3. These members are chainberedor provided with a passage. Thepassage ilk the member 1 constituting a mixing and delivery passageand the passage of the member 3 constituting a supply or inlet passage and" being provided with cold and hot" air inlets 4 and 5 respectively. The connection for the hot air inlet to a suitable source ofsupply is not shown as it will be readily understood.

gether by the screws 11, see Figs. I and III. The body member 3'fits the annular shoulder 12' at the lower end of the body member 2 and "is retained by the screws 13, see Figs. I and II. The member 2 is provided with a shoulder-like annular valve seat 13 for the throttle valve 14. The throttle valve is provided with a carbureter chamber 15 which delivreservoir 8 and delivering to the nozzle 19 carried by and projecting upwardly from the cross bar into the carbureting chamber 15. The level of the oil in the reservoir 8 and consequently in the nozzle is controlled I by the float controlled valve 20.. The stem 21 of this valve has a reduced portion or neck 22 with which the forked float lever 23 engages, the lever being pivoted at 24 on the downwardly projecting ears'25 within the inlet chamber. These ears are carried by the cover plate 26 for the inlet chamber.

The inlet chamber is provided with a nip.

ple 27 to which the supply pipe is connected. On the valve is a sleeve 28 having a downwardly projecting flange 29. The inlet chamber is provided with a well 30 and with a draw off cook 31 so that any sediment entering is collected and maybe drawn off by flushing the reservoir. The nozzle 19 has a reduced portion 32 at its upper end with which the annular carbureting chamber valve 33 coacts. This valve is mounted within the carbureting chamber to coact with the nozzle and its valve proper 34 is made conical. Below this conical part is a sleeve part 35 slidably embracing the nozzle.

-A series of air inlet openings 36 are provided with a rack 39 with which the pinion 40 on the shaft 41 coacts. This shaft 41 is provided with an arm 42, see Fig. I, having crank pin 43 thereon engaging the slot 44 in the actuating lever 45, the actuating lever being pivoted on the side of the carbureter body at 46."

A stop screw 47 limits the movement of the lever 45 in one direction. A link 48 connects the lever 45 to a suitable control lever, not shown, commonly mounted upon the steering post 49.

\Vith the arrangement described, the shifting of-the actuating lever 45 opens and closes the throttle valve and also the carbureting chamber valve and the fuel valve carried thereby.

The fuel valve is adapted for actuation independently of the carbureting chamber and throttle valves and also means are provided for adjusting the fuel valve so that its normal relation to the carbureting and throttle valve may be regulated to secure the desired richness ofmixture. To accomplish this adjustment a tubular auxiliary actuating member 50 is arranged Within the chamber 51 of the main actuating member and sleeved upon the stem of the fuel. valve. This member isheld evenly against the actuatin g'cam'52 by the spring 53 arranged within the'chamber 51 of the main actuating member, one endof the spring being arranged to engage the head 54 of .the main actuating memberand the other a flange 55 on the auxiliary, actuating member.

' The head 54 is provided with a pair of upwardly projecting segmental lugs 56 which serve as supports for the annular cam member 57. Betweenthese lugs is a slotted plate 58 having a roller 58? at one end resting on the cam. The other end of the plate has a bearing part 59 riding on the cam member. The plate has a pair of central lugs 60 which engage the under side of the head or nut 61 on the auxiliary actuating member so that it is held by the tension. of the spring 53 on the cam member. The cam member has an arm 62 connected by the link 63 to the actuating lever 64 which, for convenience, is mounted on the bracket 65 .on the steering post 49. This bracket is provided with anotched segment 66 with which the detent 67 on thelever coacts. The segment is provided with suitable indicia indicating the position of the fuel valve.

It'will be observed that the fuel valve or auxiliary actuatingmechanism is carried by the main actuating member so that normally the fuel, carbureting chamber and throttle valves are operated together. The fuel valve may, however, be operated independently to increase or decrease the richness of the mixture for normal running or for starting. \Ve also provide means for adjusting the fuel valve in its normal relation to the throttle and mixing chamber valves. In the structure illustratedthis consists of the adjusting screw 68 threaded into the upper end of the auxiliary actuating member to engage the end of the fuel valve stem. A coiled spring 69 acts upon the fuel valve stem to hold against its adjusting screw. .A cap 70, carried by the head of the main actuating member incloses the upper end of the auxiliary actuating member and the parts mounted on the head of the main actuating member.

The air inlet valve 6 is controlled by the lever 71 mounted on the bracket 65 for the lever 64, the opposite sideof the segment 66 being notched to coact with the detent of the lever 71. These levers are both mounted on the same pivot 72, the lever 71 being connected by the link 73 to the arm 74 of the valve 6. The temperature of the air passing through the 'carbureter may be satisfactorily controlled by this arrangement. f

The section 1 of the body is provided with a water jacket 75 so that it may be heated if desired. Y

By this arrangement of parts we'provide a structure in which efl'ective control of the fuel is had for starting and efl'ective regu:

lation for normal running andastructure in which proper proportions may be maintained throughout varying running conditions. 'Certain features of the structure herein described are disclosed and broadly claimed in Letters Patent No. 1,107,713, issued tous August 18, 1914, the present structure being a modification and in some respects an improvement upon the structure there illustrated.

We have illustrated and described our present improvements in the form in which we have embodied the samein practice. We have not attempted to illustrateor describe various modifications which we. contemplate as we believe the disclosure made will enable those skilled in the art to embody our improvements as taste or conditions may dictate.
